'IMPROVEMENT IN DEVICES FOR. OPERATING CHURNS.

Specification forming part of Letters Patent No. 39,] 07, dated July 7, 1863.

To all whom it may concern:

,Mode of Operating Reciprocating Churns;

and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this speccation, in which- Figure l is a side sectional view of my invention, taken in the line x x, Fig. 2; Fig. 2, a plan or top view ofthe same.

Similar letters of reference indicate corresponding parts in the two ligures.

The object of this invention is to obtain a means whereby reciprocating churns-that is to say, those which are provided with rising and falling dashers-may be operated With greater facility than by the ordinary application of the hands to the dash-rod.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents a churn of the usual reciprocating kind 5 and B is the dash-rod, the upper part of which is connected. by a pin, a, with.

an arm, C, attached to a rock-shaft, D. The arm (l is perforated with a series of holes, b, and the upper part ofthe dash-rod is also perforated with a series of holes, c, as shown in Fig. 1. The rock-shaft D is supported by an upright framing, E, which may be constructed in any proper manner, and has a pendulum, F,

' connected toit, the weight of the bob G, of

which should begoverned by the size of the dash H at the lower end of the rod B.

I is a treadle, which is attached to the platform J, on which the churn A and framing E are placed. This treadle is connected by a cord or chain, K, to a spring, L, which is attached to the rock-shaft D. The spring L may be formed of a straight metal bar of steel or other elastic metal, or a piece of elastic wood would answer-such as hickory, for instance. In the drawings the spring is represented as being made of a cylindrical metal rod bent in loop form.

The operation will be readily seen. The

foot of the operator is applied to the treadle I,

the latter giving motion to the rock-shaft D, and the arm C giving a reciprocating movement to the dash-rod B. The pendulum F equalizes the movement of the dash-rod, performing a function similar to a ily-wheel on a crank-shaft, and the spring L serves to prevent any sudden jerks of the treadle, also equalizing the movement of the dash-rod. The length ofthe stroke of the dash-rod may be regulated, as desired, by inserting the pin a in a hole, b, nearer to or farther from the rock-shaft D, and by inserting the pin a in a hole, c, in the dash-rod nearer to or farther from the dash H, the latter may be raised or lowered to suit the height of the cream in the churn. By this arrangement of means the churn may be operated with the greatest facility. The dashrod B is provided with a joint, d, to compensate for the curvilinear movement of the arm C. A

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

' The combination of the springL and treadle I with the rock-shaft D, weighted pendulum F, adjustable arm C, adjustable pivoted dasher-rod B, and churn A, all in the manner and for the purpose herein shown and described.
